Recently my BumbleBeast developed a Weird noise, a Rattle Sound that was only noticeable at idle; So I checked it and I originally thought that it had Worn A/C Compressor's Ball Bearings... (as you can read ~►Here) ...but the A/C kept working fine.

So, I was about to install my Brand New SJR Lift kit for the front only... (as you can see ~►Here) ...and I decided to Remove the Weberized EA82 engine from my BumbleBeast to check it carefully and make the lift install easier, also, I got Rid of the Timing Belts' Covers at all... (as you can Read ~►Here) ...Because I thought that the Weird Noise source could be a Worn Timing Belt Tensioner's Ball Bearing.

Then with the Engine out, I Discovered that the Source of the Weird noise was the Main Fan, the one attached to the Water Pump's Pulley, also known as "Mechanical" fan; so my BumbleBeast's A/C compressor is fine.

A Little bit of Background History: The Fan clutch it had, failed around year 1993, so I decided to Fix the Fan by Drillin' a 1/4" Hole thru the Fan clutch and insert a 1/4" Twisted wire into that hole and Welded the wire to the Fan's Base.

It worked good since then... but now, several years later; the Hole I Drilled on the Fan Clutch's area, became Wider and the Welded wire is Loose, also the Fan is Loose, so that thing is Ruined...

I Need to obtain a New Fan for that, I'll Like to Keep the original fan setup, but here comes the Question:

is there any Fan that fits the Pulley on my EA82 that comes without Fan Clutch?

...or is Better idea to Replace the pulley-driven Fan, retrofitting an Electric Fan?

Someone told me that the lack of the Fixed fan on the Waterpump's Pulley will made to the Waterpump to last longer and also will help to the Engine to gain a good couple of more Hp...

is that True?

Yes and yes. You also gain throttle response and it makes changing timing belts and other maintenance easier. If you ever get into water that deep enough to hit the fan, you don't have to worry about the blades bending into the radiator. This is more of a problem on fixed blade fans, but I've seen it happen on clutch fans too.

I hate clutch fans and I never hesitate to tear one out and swap it for an electric. The thing I don't like about fixed blade fans is that they are on, %100 of the time, which means %100 drag @ %100 of the time...the thing I like is that they are %100 reliable, nothing but air moving steel. Clutch fans can go out with no warning or notice, they can cause all sorts of noises when they do and they can never deliver %100 of the energy put into them because the clutch slips. Electrics only turn when needed and can be set on delay timers so your motor can warm up asap, or put on post timers so they can still cool the motor after it turned off. The effeciency of electric fans is much higher than either fixed or clutch fans so you might see a MPG or two increase and maybe a HP or two. You can also turn electric fans off manually for water crossings to avoid stressing/breaking things.

I'm running a 12" Hayden pusher fan with a hayden adjustable thermo switch I got at O'rielly's for $110. It draws 8amps. I plan on running another as a backup ,and to take some work load off the other one.

Yes and yes. You also gain throttle response and it makes changing timing belts and other maintenance easier. ...

Great!, Now I'm Sold with the idea to Remove the mechanical fan and install an electric fan there.

Any Little gain in Hp, Throttle Response, or Torque in these EA82's, worth the effort.

I guess I Can Remove Both and use a Big Single electric fan, Wired with the actual electric fan Wiring, then the electric one should turn on when:

The A/C is activated.

The Engine's Temperature reaches certain temperature.

But my BumbleBeast starts the electric fan when Temp reaches Above the Middle mark, and I Don't Like That due to the Head Gaskets' issues on these engines; I'll Like to keep the engine Cooler, especially if I remove the mechanical fan.

Now with the mechanical fan constantly spinning, it Usually Runs around 1/4 temp gauge; so if I get rid from it, I Must change the Thermo Switch in order to avoid overheatings... isn't it?

Are those thermoswitches Standard? ... So I could find a Lower temp thermo Switch and swap the actual one.

I have a very slim EA81 fan in place of the original engine driven fan. I have it wired with a relay, and the other electric fan's ground completes the circuit. So whenever the OEM fan is grounded via A/C or thermo-sensor, both run. I also replaced the water pump pulley studs with bolts for more clearance.

Sure!I feel pretty good about it. It's designed to upgrade a car with mechanical fans. Much better than my ailing electric fan. It was very tired. This fan is also reversible for use on the other side of the radiator.Alabama summers get pretty warm too. And this did fine.I'll try and find the paperwork on it.

Its the completely stock fan. I dont have A/C on my car, never really wanted it either... A/C to me is Windows down at 65 mph haha.

The fan is pretty big. You can get an EA81 fan on the empty spot in my radiator... Much thinner. And I will put one on there when I swap in a rebuilt EA82, just to keep things extra cool. Have it wired to a switch that I can turn it on in the summer on hot days while in traffic kinda thing.
